Be it known that I, HARRY C. ANDERSON,

residing in Hampton township, in the county of Allegheny and State ofPennsylvenia, a citizen of the United States, have invented ordiscovered certain new and useful Improvements in Treating GaseousFluids, of which improvements the following isa specification.

The invention described-herein relates to the removal of dust trom liy.ids and thecondensation or elimination lof deleterious gases, etc., andhas for itsl object the. vproduction of a 'tiow of the air, gases, etc.,si-

multaneous with and through the agency oit y the means employed for thecooling and purifying of the air, gases, etc.

The invention is hereinafter more fully described and claimed.

In the accompanying drawings forming a part of this specifica-tionFigure 1 is a sectional elevation of my improved apparat-us; Fig. 2 is atop plan View of the samegFig.

3' is a sectional view on a plane indicated by the line III-III Fig. 1;Fig. 4 isa transverse section on a plane indicated bythe line IV-IV Fig.3; and Fig. 5 is a sectional plan View illustrating a. modification .inthe arrangement ofthe flues or vertical passages in my imp'rovedapparatus.

. While I have shown a form of apparatus especially adapted for treatinggases from furnaces, roasters, etc., it is also adapted for otherpurposes as cleansing and cooling air for ventilation purposes.

{The apparatus as shown is provided with .a series of vertical tlues'orpassages 1, 2, 3,

etc., the number, length and transverse dimensions of which canbe variedin accordance with vthe volume and condition of the gases, etc., to betreated. The gas or other fluid to be treated is introducedinto thefirst flue l of the series by a flue or tube 9 lovver end. This pointot' introduction is.

to their upper ends, and the latter flue is leading from a' roaster,furnace or other source preterably at a point adjacent to its preferredwhen treating hot gases, etc., as advantage can be taken of theirbuoyancy to edect their -initial movement, but it- Will be understoodthat the gases, etc., maybe 'introduced at any desired point.

The' uptake line 1 is connecteflby an opening 10 to the dovvntake iue 2adjacent connected by'anopening 11 to the adjacent uptake flue 3, at oradjacent to their lower ends, and so on through the series.v The finesare formed with open lower ends, but communication between the lowerends of the uptake tlues and the succeeding down take tlues isprevented. This sealing oli of adjacent lues is effected in theconstruction V- shown herein by extending the Walls 12 between saidfiues below the surface of the liquid in the basin 13 over which thefines are built. The upper ends ot the uptake iues are closed, and inthe dovvntake fines .preferably at a-point above the openings 10 throughwhich the gas', etc., passes into the downtake iiues, suitable means 14are arranged for the introduction of a spray or rain-like flow of aliquid suitable for cleansing the gases. etc. This rain-like flow orspray lshould completely lill transversely the doWnt-akes, so 'as toinsure that the particles of liquid will operate collectively somewhatlike a piston forcing the gases down through the flue. As will bereadily understood by those skilled in the art, that what might becalled an attenuated spray, z'. e., thedrops or particles substantiallyseparat-ed, will not Vhave any material influence in causing gases tomove downwardly, but Where the spray is ldense-fillingv the'flue orpassage and the drops or .particles closely adjacent, such drops orparticles will have Whatlmight be termed a frictional drive on the.gases and the entire body will as stated operate somewhat like a pistonand push the gases down.

As the spray or drops of liquid drop through the downtake flue, thefrictional contact vvith the gasestetc., will cause the latter tomovedown in the same direction to the lowerl end of the downtake from whichthe gases, etc., will escape through the opening 11 into the uptake,Whilel thev liquidV will drop into the basin 13. While the gases, etc.,and the liquid are moving together the latter will Wash out ormechanically remove the dust 'and any solids which may be mingled withthe gases, etc., and deposit the same inthe basin. As the liquid iscooler than the gases, etc., a condensation of the? condensable portionof such gases- Will be, effected.

While itis believed that the gases, etc.,

and liquid Will be sufficiently intermingled While passing through thedowntakes a more,

intimate mixing of the two may be effected by the arrangement ofi' oneor more shelves 15 in the downtake preferably adjacent to the lower endsot' the latter, so that there will be a thorough intermingling ot gasesand liquid just before the complete separa tion ot the gases and liquid,etc. due to the escape. of the gases through opening l1 intn the nextuptake as stated.

ln order to reduce the quantity of liquid flowing along the walls of thedowntakes, said walls are provided with rows ot pro jections 16 soconstructed that any liquid lodging on the projections will flowinwardly to points on the undersides of the projections and will droptherefrom clear of the walls of the downtake.

'lhe passage of the liquid which should fill the flue transverselj.'through the downtakestdrawing with it the gases, etc., will reduce thepressure in the upper 'ends of the uptakes and downtakes thus inducing amore rapid fiow through the uptakes and into the downtakes than would bedue to the buoyancy of the gases, etc., and hence in the upper portionsof the downtakes the flow of the gases, etc., will be more rapid thanthat of the liquid, the speed of which is accelerated v.and 'in thelower 1j ortion becomes greater than that of the air or gases.- Henceduring a large portion of the distance trav ersed by the gases, ete.,and/the water, there will be a rubbing as it were of one on the other,and as a consequence thereotl a more effectual cleaning and condensingaction on the gases.

As will be readily understood the gases, etc., are being constantlypulled from uptakes and the gases, etc., are being placed under more orless pressure in the lower ends of the downtakes, which pressure tendsto push the gases, etc., up through the next succeeding uptake. From theforegoing it will be seen that gases in the uptakes are subjected to adowntake and to a push by the preceding downtake.

It desired steam or other fluid which will affect chemically orotherwise some oraall the constituent elements of the gases from afurnace, etc., may be injected by means of the pipe 17 and nozzles 17apreferably into the uptakes adjacent to their lower ends As'betorestated the fiues 1, 2, etc., are built over a basin 13, in whichsufficient liquid to .seal the lower ends of the uptakes from thedowntakes. Int-o this basin will fall the cleaning liquid carrying alldust or other solid materlalsi'collected from the gaseous fiuids passingthrough the lues. A covered trough 18 extends a suitable distance fromthe basinfand an endless chain 19 provided with Scrapers 2O is arrangedin the trough and extends into the asin sutlieiently far to enable theScrapers to pull toward the next succeedingFV is maintained for sodischarging a provided at its outer end with an inclined bottom portion21 extending above the level of the liquid maintained in the trough. The

endless chain and Scrapers are so arranged in the trough that thescrapers will move the solid material up the inclined portion 21 anddischarge over the end of the trough. The

trough is made ot such a depth that a passage 22 is formed between thesurface of the water in the trough andthe top oftthe latter, for thefiow ot uncondensable or unabsorbed gases from the last downtake to theoutlet pipe 23. The outer end of the passage E22 is closed by a walldepending trom the top of the trough and extending below the level ofthe liquid'in said trough.

It is characteristic` ot' my improvement that the cleansing andpurifying of the air orgases, etc., is effected not only without anyinterference with the natural tlow thereof, but that the movement of thefiuid treated is due to a very large extent to such cleansing andpurifying liquid, which prac tically fills the downtakes transverselyand so operates on. the entire volume of gas as to cause it to movedownwardly with the liquid. And further this falling liquid effects aremoval of the solids carried by the Huids, a condensation of portionsof such fluids, and when. suitable liquids are employed will absorbrcertain of the constituents of the gas. Hence inyimprovement while welladapted for other purposes is especially adapted for use in connectionwith the treatment of material as the roasting and reductionl of ores inwhich deleterious gases, etc., are produced.

In Fig. 5 is shown a circular arrangement of the fines, which in somecases may be desirable where there is not sufiicient room for anextended or tandem arrangement as shown in Fig; 1. A

I claim herein as my invention:

l. The method herein described of causing gaseous fiuids to traverse aseries of alternating uptake and downtake filles, which consistsl indrawing the gaseous fluid from one uptake and forcing it into the lowerend of another uptake by the `action of a liquid in a finely dividedcondition falling through the downtake,`the cross-sectional area of thefalling liquid being approximately-equalto the cross-sectional area ofthe downtake, whereby the fallingliquid will have a propulsive actiononthe gaseous Huid.
